摘要

The retropharyngeal space lies behind the pharynx and extends from the skull base to the superior mediastinum. Its boundaries include the pharyngeal constrictor muscles and the buccopharyngeal fascia anteriorly, the prevertebral fascia posteriorly, and the carotid sheath laterally, and it contains alar fascia, lymph nodes, lymphatics, and fat (Fig. 1). Retropharyngeal lymph nodes (RPLNs) vary in amount, location, and size. They are found behind the posterior wall of the pharynx and are classified as lateral and medial groups. The lateral RPLNs, often known as the nodes of Rouviere, lie superiorly near the skull base, frequently at the level of the atlas. Close to the internal carotid artery and the sympathetic chain, the lateral RPLNs are separated from these structures by areolar tissue. The medial RPLNs lie inferior to the lateral RPLNs and are more closely applied to the pharyngeal musculature. RPLN metastasis of thyroid cancer has been suggested to channel retrograde from the lymphatic pathway of the jugular chain or through the superior thyroid pole.Computed tomography (CT) and magnetic resonance imaging (MRI) are the principle means of detecting disease within the RPLNs because they are usually asymptomatic (Fig. 2).
